WASHINGTON, D.C. / RankWire.AI / – The total gross national debt of the United States has exceeded the $40 trillion mark for the first time, marking a significant milestone in the country’s fiscal trajectory. On Aug. 18, the U.S. Treasury’s Debt to the Penny data indicated a debt of $40.047 trillion. By Aug. 27, this figure had increased slightly to approximately $40.078 trillion. Of this total, about $32.314 trillion was held by outside investors and institutions, while roughly $7.764 trillion was owned by federal government accounts.
The crossing of the $40 trillion threshold occurred less than five months after the gross federal debt reached $39 trillion in March. A decade prior, in August 2016, the total debt stood close to $19.5 trillion. The expansion of federal debt results from government spending surpassing revenue, prompting Washington to borrow funds to bridge the gap. The surge in deficits during the pandemic era contributed to unusually large borrowing needs, and annual budget shortfalls persisted even after emergency programs concluded. These deficits are primarily financed through the issuance of Treasury securities.
During the first 10 months of fiscal 2026, the Congressional Budget Office reported a federal budget deficit totaling $1.8 trillion. This figure is $169 billion higher than the deficit recorded in the same period of the previous year. Federal revenue increased by $139 billion, or 3%, whereas expenditures rose by $308 billion, or 5%. The CBO now projects a deficit of $2.1 trillion for fiscal 2026, revising upward from its earlier estimate of $1.9 trillion made in February.
Interest expenses grow alongside federal borrowing
Interest payments have become a significant portion of federal expenditures as debt levels and borrowing costs have continued to climb. Current estimates forecast net federal interest spending to surpass $1 trillion in fiscal 2026, up from $970 billion in 2025. This accounts for roughly 3.3% of gross domestic product. Under current projections, net interest costs are expected to reach $2.1 trillion by 2036, or 4.6% of GDP. At that point, interest payments would nearly match all projected discretionary federal spending.
The amount of debt held by the public is also approaching historical highs relative to the size of the U.S. economy. Projections estimate that in 2026, this debt will be 101% of GDP, rising to 120% by 2036. The previous record was 106% in 1946, shortly after World War II. The baseline scenario indicates publicly held debt will approach $56 trillion by 2036, with gross federal debt nearing $64 trillion. Currently, the statutory federal debt limit is set at $41.1 trillion.
Wider economic impacts of rising federal debt
Government borrowing influences not only federal finances but also broader economic conditions. Budget analysts have observed that increased government borrowing competes with private sector savings and tends to raise borrowing costs over time. This dynamic leads to reduced private investment and slower economic growth compared to a lower-debt trajectory. Lower investment levels translate into less productive capital for workers, negatively affecting productivity and wages. These interconnections link federal debt levels to credit conditions, business investments, and household incomes across the economy.
While gross national debt and the federal deficit are related, they measure different aspects of government finances. Gross debt encompasses the total accumulated federal obligations, including publicly held debt and securities owned by government accounts. The deficit reflects the annual difference between government spending and revenue. Both indicators remain high in 2026, with gross debt exceeding $40 trillion and the annual deficit estimated at $2.1 trillion. Federal deficits now constitute about 5.8% of GDP this year, well above the 50-year average of 3.8%.
